2. Description of the Related Art In recent years, the number of elderly people with dementia has increased as their lifespans have increased and their aging has progressed. For this reason, wandering elderly people, as well as those who need to consider entering and leaving the house, such as infants and disabled persons ( There is a demand for protection measures against wanderers. In particular, when a wandering person is in a nursing facility or at home, it is necessary to constantly monitor a caregiver such as a family or a home helper or a family living together (hereinafter referred to as a resident). In that case, it is difficult for the caregiver to accompany the wandering person for 24 hours. Therefore, as a method of detecting a wandering resident trying to go out of the house, for example, JP-A-8-65413, JP-A-2000-0808
As disclosed in Japanese Patent No. 1488, as a talisman, a transmitter that generates radio waves or visible light having a predetermined frequency is used as a talisman, or attached to clothes so that the transmitter cannot be identified. There is a method of receiving a radio wave or a visible light from a transmitter at an entrance to inform a resident of the vehicle. Also, in order to monitor the entry and exit of wanderers from the entrance of the house and to detect the intrusion of suspicious persons, for example, as disclosed in Japanese Patent Application Laid-Open No. 07-079291,
There is a method in which a video camera is provided near an entrance and a resident is notified by generating an alarm using an alarm generation device or the like when a wandering person or a suspicious person is detected.

[0003]

However, in a conventional method of detecting a wandering person approaching an entrance by carrying a transmitter to a wandering person, the wandering person finds the transmitter and removes it, or removes the transmitter. They sometimes hate mobile phones and cause problems. For this reason, there has been a problem that the monitoring is interrupted or becomes impossible, and the resident cannot sufficiently monitor the outside of the wandering person. In addition, when a video camera is provided near the entrance to detect a wandering person or a suspicious person, it is necessary to take a video with a video camera at all times and record it on a video. The present invention has been made in view of such circumstances, and it is possible to detect a wandering person approaching an entrance and exit and detect a suspicious person entering from an entrance and exit without having to carry a transmitting device to a wandering person. It is intended to provide a person monitoring device.

Thus, when a wandering person carrying a portable radio transmitter approaches the entrance, the human body detection unit detects a person, and the radio reception unit receives a weak radio wave including a predetermined ID signal from the portable radio transmitter. Then, the control unit confirms that the person is a wandering person, and the alarm generation unit issues an alarm in response to the alarm signal from the control unit. Therefore, it is possible to detect that the wandering person is near the entrance. Also, only when a human body is detected,
Since a weak radio wave including a predetermined ID signal can be received, normally, when no wandering person is near the doorway, the power of the wireless receiving unit is turned off, and there is a power saving effect.

According to a third aspect of the present invention, there is provided an entry / exit person monitoring device which intermittently emits a weak radio wave including a predetermined ID signal, and a monitoring device provided at or near an entrance / exit.

It is a lineblock diagram of an entering and leaving person monitoring device concerning a 3rd embodiment.

As shown in FIGS. 1-3 (A) and (B),
Entry / exit monitoring device 10 according to the first embodiment of the present invention
Is provided with a box-shaped monitoring device main body 12 at or near an entrance 11 such as an entrance. It is separate from the monitoring device main body 12 and has a diameter of, for example, 50 mm and a thickness of 10 to 20 mm.
Power supply 13 consisting of batteries in a plastic case
A and a light weight of about 30g containing the radio wave transmitting unit 13B,
In addition, a portable radio transmitter 13 that intermittently emits a weak radio wave including a predetermined ID signal including an identification signal for identifying the resident B is provided. The transmission output of the weak radio wave is, for example, 500 μV / m or less, the transmission period is intermittently transmitted about once every 0.7 to 1 second, the power consumption is about 5 μA, the power consumption is extremely small, and the life of the battery is 1-2. It is about a year.

The monitoring apparatus main body 12 includes, for example, an entrance 11
The radio receiver 15 receives a weak radio wave including a predetermined ID signal transmitted from the portable radio transmitter 13 whose distance L from the mobile phone approaches a range of about 1.5 to 2 m. A human body detection unit 16 including an infrared sensor (also referred to as a passive sensor) for detecting the wanderer A when approaching the vehicle and a power supply unit 14 are provided. In addition, the human body detection unit 16 is configured such that the distance L from the entrance 11 is 1.5 to 2 for example.
A human body in a range of about m can be detected. However, the distance that the wireless receiver 15 can receive and the human body detector 16
Need not necessarily match the detectable distance.

The monitoring device body 12 has a control unit 17 comprising a microcomputer which receives the outputs of the radio receiving unit 15 and the human body detecting unit 16 and issues an alarm signal under predetermined conditions.
And issues an alarm in response to an alarm signal from the control unit 17.
For example, an alarm generator 18 including an electronic buzzer is provided. The predetermined conditions under which the control unit 17 generates an alarm signal include:
The wireless receiving unit 15 is in a non-receiving state of the ID signal from the portable radio transmitter 13, and the human body detecting unit 16 detects a human body. That is, the portable radio transmitter 1
The portable radio transmitter 13 is provided on condition that a person carrying the device 3, for example, the resident B is not at the entrance 11 and that a human body that is a wanderer A approaching the entrance 11 is detected. When the wireless receiver 15 receives the ID signal from the portable radio transmitter 13, the alarm signal is stopped. Control unit 1
7 is provided with a wireless receiver power switch 19 for turning on the power for operating the wireless receiver 15 when the human body detector 16 detects a human body.

From the alarm generation unit 18, for example, a first alarm sound composed of a relatively loud sound (peak sound) that can be heard even when there is daytime noise, and a relatively small sound (pip sound) heard when the night is quiet. ) Is generated. An alarm sound changeover switch 20 is connected to the control unit 17. The alarm sound changeover switch 20 includes a first contact 21 for outputting a first alarm sound and a second contact 22 for outputting a second alarm sound. And an off contact 2 for stopping the first and second alarm sounds
3 so that one of the first contact 21 and the second contact 22 can be selected to select the type of alarm. When the first and second alarm sounds are being output, the alarm sound changeover switch 20 electrically generates an alarm continuously for a predetermined time even if the off-contact 23 operates mechanically. Thus, the wanderer A cannot stop the alarm.

The monitoring device main body 12 is illuminated by an output from the human body detecting section 16 and flashes, for example, a human body detecting lamp 24 composed of a red LED (light emitting diode).
And a wireless detection lamp 25 made of, for example, a green LED, which is turned on by the output from the wireless receiving unit 15 to perform flash display. Thus, when the monitoring device main body 12 is installed near the entrance 11, the position of the person carrying the portable radio wave transmitter 13 in advance from the monitoring device main body 12 and the operation of the human body detection light 24 and the radio detection light 25 are controlled. Is confirmed, the detection range of the human body by the human body detection unit 16 and the wireless reception unit 15 is confirmed, and the optimal installation position of the monitoring device main body 12 can be determined. When the voltage of the battery drops, the red human body detection lamp 24 blinks to notify the replacement time. As described above, since the power consumption of the monitoring device main body 12 is extremely small, the monitoring device main body 12 can be miniaturized. Can be formed, and the installation location can be attached to an arbitrary position such as a wall or a door near the entrance 11 with a double-sided adhesive tape or the like, and installation work is substantially unnecessary.

Here, the operation of the entering / leaving person monitoring apparatus 10 according to the first embodiment of the present invention will be described with reference to the flowchart shown in FIG. (1) The resident B carries the portable radio transmitter 13 in advance. Further, the alarm sound switch 20 selects one of the first contact 21 and the second contact 22 in advance. (2) As shown in FIG.
Approaching the range of about 1.5 to 2 m from the human body detection unit 1
6 detects the loitering person A, inputs the human body detection signal to the control unit 17, and turns on the human body detection lamp 24. Control unit 17
Receives the human body detection signal, turns on the wireless receiver power switch 19, and outputs a weak radio wave from the portable radio transmitter 13 for a predetermined time, for example, 1 to 5 seconds (intermittently about once every 0.7 to 1 second). (Constant transmission) is confirmed, and the wireless receiving unit 15 is set to a state in which radio waves can be received. (3) When a weak radio wave is not received within a predetermined time (for example, about 1 to 5 seconds) after receiving the human body detection signal from the human body detection unit 16, the alarm generation unit 18 generates an alarm. The alarm generator 18 generates either the first alarm sound or the second alarm sound selected by the alarm sound switch 20.

(4) As shown in FIG. 3 (B), when the resident B carrying the portable radio transmitter 13 approaches the range of about 1.5 to 2 m from the entrance 11 after hearing the alarm sound, the radio The receiving unit 15 receives a weak radio wave including a predetermined ID signal (ID code) transmitted from the portable radio wave transmitter 13 and inputs the weak radio wave to the control unit 17. (5) The control unit 17 confirms the ID signal, generates a radio wave detection signal, stops the generation of the alarm from the alarm generation unit 18, and turns on the green wireless detection lamp 25. In this state,
The resident B approaching the entrance 11 observes the wanderer A near the entrance 11 and is in a state where a desired response can be made. In addition, it is possible to detect not only the wandering person A but also a family member who intends to go out without permission. (6) The wanderer A approaches the entrance 11 and the alarm generation unit 18
The alarm is stopped for a predetermined time, for example, about 30 seconds to 1 minute after the alarm is generated. (7) After the alarm is stopped in each of (5) and (6), the state of (2) is set.

As shown in FIG. 5A, as an application example,
For example, when the locked door of the doorway 11 is unlocked by a special device, so-called picking, and the suspicious person C opens the door and enters the door, similarly to when the wanderer A approaches the doorway 11, the human body is detected. The unit 16 detects the suspicious individual C, inputs a human body detection signal to the control unit 17, and turns on the human body detection lamp 24. The control unit 17 receives the human body detection signal and turns on the wireless reception unit power switch 19 to turn on the wireless reception unit 15.
